Description
The AT29C020 is a 5-volt-only in-system Flash programmable and erasable read only
memory (PEROM). Its 2 megabits of memory is organized as 262,144 bytes. Manu-
factured with Atmel’s advanced nonvolatile CMOS technology, the device offers ac-
cess times to 90 ns with power dissipation of just 220 mW over the commercial tem-
perature range. When the device is deselected, the CMOS standby current is less
than 100
μ
A. Device endurance is such that any sector can typically be written to in
excess of 10,000 times.
